Preferably, the mounting clip column 3 is composed of a bottom clip column 302 at the bottom of the mounting clip column 3, a screw column 306 at the top of the clip column 302, a top clip column 301 in the middle of the screw column 306, a screw cap one 305 at the top of the screw column 306, a bottom column 304 at the top of the front of the bottom clip column 302 and a penetrating column 303 in the middle of the front of the top clip column 301, when a user wants to mount the handrail main body 1, the user needs to unscrew the screw column 306 through the screw cap one 305, then the user holds the screw column 306 to drive the bottom clip column 302 to be clamped at the bottom of the stair 2, then holds the screw cap one 305 to rotate downwards at the top of the screw column 306, and drives the top clip column 301 to move downwards when the screw cap one 305 rotates downwards, and when the screw cap one 305 cannot rotate, the top clip column 301 and the bottom clip column 302 respectively abut against the upper end and the lower end of the stair 2, and when the mounting clip column 3 is fixed at both sides of the stair, the user is handheld bracing piece 4 again and is fixed through laminating between passing through post 303 and foundation 304, and the user just can install railing main part 1 on stair 2, and fixes on stair 2 through the cardboard mode because of installation card post 3, so when installation card post 3 takes off, the surface of stair can not produce the condition of any groove and damage to also repair with the user later stage, the time that the user later stage that significantly reduces will spend.

Preferably, the assembling mechanism is composed of the installation clamping column 3, the supporting rod 4, the telescopic cylinder 5, the inner column 6 and the installation frame 7, when the installation clamping column 3 is fixed on the stairs, the user can hold the supporting rod 4 again to insert into the installation clamping column 3, then the user can sleeve the installation frame 7 into the middle of the supporting rod 4 from the top of the supporting rod 4, and fix the installation frame 7 in the middle of the supporting rod 4 through a screw II 704, meanwhile, the user can pull out the inner columns 6 at two sides of the telescopic cylinder 5 to the length required by the user, then the inner columns 6 at two sides of the telescopic cylinder 5 are respectively lapped in the placing grooves 702 of the corresponding installation frame 7, the user can normally use the handrail main body 1, the handrail main body 1 can be disassembled into various parts according to the same principle and according to the opposite steps, thereby the user can conveniently carry the handrail, meanwhile, the operation mode of the assembling mechanism is simple, and greatly, thereby greatly improving the portability of the utility model.

The working principle is as follows:

firstly, when a user wants to install the balustrade body 1, the user needs to unscrew the screw column 306 through the first screw cap 305, then the user holds the screw column 306 to drive the bottom clip column 302 to be clipped at the bottom of the stair 2, then holds the first screw cap 305 to rotate downwards at the top of the screw column 306, and drives the top clip column 301 to move downwards together when the first screw cap 305 rotates downwards, and when the first screw cap 305 cannot rotate, it means that the top clip column 301 and the bottom clip column 302 are respectively stuck at the upper end and the lower end of the stair 2, and when the installation pillars 3 are fixed at the two sides of the stair 2, the user holds the support rod 4 to stick and fix between the through column 303 and the bottom column 304, the user can install the balustrade body 1 on the stair 2, and because the installation pillars 3 are fixed on the stair 2 through the way of the clip board, when the installation pillars 3 are taken down, the surface of the stair can not generate any groove and damage, so that the later repair of a user is not needed, and the time spent by the user in the later period is greatly reduced;

then, when the bottom of the stair 2 is directly connected with the ground and the mounting clamping column 3 cannot be used, the mounting base 9 and the stair 2 can be used for fixed mounting, a user firstly fixes the mounting base 9 on the top of the stair 2 through a first screw 10, then holds the supporting rod 4 to be inserted into a groove in the top of the mounting base 9, holds the bolt 11 to penetrate through the top of the mounting base 9 and the supporting rod 4, holds the nut II 12 to screw the bolt 11, the base 9 and the supporting rod 4 cannot be separated, and the fixing property between the base 9 and the supporting rod 4 is greatly improved;

then, after the mounting clip column 3 is fixed on the stairs, the user can insert the mounting clip column 3 by holding the supporting rod 4 with hands, then the user sleeves the mounting rack 7 into the middle of the supporting rod 4 from the top of the supporting rod 4, and fixes the mounting rack 7 into the middle of the supporting rod 4 through the second screw 704, meanwhile, the user needs to pull out the inner columns 6 at two sides of the telescopic cylinder 5 to the length required by the user, then the inner columns 6 at two sides of the telescopic cylinder 5 are respectively lapped in the placing grooves 702 of the corresponding mounting rack 7, the user can normally use the handrail main body 1, and the handrail main body 1 can be disassembled into various parts according to the opposite steps, so that the handrail main body is convenient for the user to carry, meanwhile, the operation mode of the splicing mechanism is simple, the user can also be greatly convenient to splice quickly, and the portability of the utility model is greatly;

next, when the user adjusts the length of the telescopic cylinder 5 correspondingly, the user can firstly unscrew the first clamping column 8 from the top of the telescopic cylinder 5 and take the telescopic cylinder 5 down, then hold the inner column 6 by hand and pull the telescopic cylinder 5 outwards, and after the required length is pulled, the user can screw the first clamping column 8 into the telescopic cylinder 5, so that the first clamping column 8 is clamped in the telescopic cylinder 5 by the first clamping column 8 and cannot move, and the length formed by the telescopic cylinder 5 and the inner column 6 can be adjusted greatly according to the actual condition due to the stretchability between the inner column 6 and the telescopic cylinder 5;

finally, when the user will be to the mounting bracket 7 highly adjusting that the bracing piece 4 was placed, the user can hand two 704 screws and outwards screw out from the bracing piece 4 department of through hole 703 inside, make the relation of connection of mounting bracket 7 and bracing piece 4 loosen, and the diameter of through hole 703 because of in the middle of the mounting bracket 7 is greater than the diameter of bracing piece 4, so the user just can hand mounting bracket 7 and well prop up at bracing piece 4 and reciprocate, and when moving suitable position, the user only need hand two 704 screws to the bracing piece 4 in the middle of the through hole 703, mounting bracket 7 just can fix on bracing piece 4, thereby also make things convenient for the user to adjust mounting bracket 7 from top to bottom in bracing piece 4 department greatly, this is exactly the theory of operation of this kind of adjustable stair temporary protection railing.

It is obvious to a person skilled in the art that the invention is not restricted to details of the above-described exemplary embodiments, but that it can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim concerned.

Furthermore, it should be understood that although the description is made in terms of embodiments, not every embodiment includes only a single embodiment, and such description is for clarity only, and those skilled in the art will recognize that the embodiments described in the various embodiments can be combined as appropriate to form other embodiments as would be understood by those skilled in the art.
